Int. Cl. A47f /08; A47g 29/02 US. Cl. 248311 Claims ABSTRACT OF THE DISCLOSURE This invention appertains to the art of mountings on apertured boards and more specifically to a novel anchor for shelves or the like.

Prior art structures presently known to applicants provide merely hooks and the like for mounting on aperture boards. There are several sizes sold depending upon the weight they are to support and the thickness of the support board.

A general object of the invention is to provide a novel anchor for securing a shelf bracket or the like to a mounting board in which the anchor element has parts wedging with the board to provide a secure, tight assembly.

A further object of the invention is to devise a novel anchor incorporating a transverse portion and a pair of legs, the legs having angled portions adapted to embrace a portion of the board therebetween to draw the transverse portion toward the board and thus hold the retained supported structure tightly against the board.

These and other objects and advantages inherent in and encompassed by the invention will become more apparent from the specification and drawings, wherein:

FIGURE 1 is a fragmentary perspective view of-an apertured board with the invention mounted thereon, parts being shown in transverse vertical section;

FIGURE 2 is a transverse vertical sectional view of the structure taken substantially on line 22 of FIG- URE 1;

FIGURE 3 is a sectional view taken substantially on line 3--3 of FIGURE 2;

FIGURE 4 is an enlarged sectional view taken generally on line 44 of FIGURE 3;

FIGURE 5 is a top plan view of the mounting element in unstressed condition; and

FIGURE 6 is a fragmentary bottom view taken generally along line 66 of FIGURE 2.

Describing the invention in detail, the apertured wall board generally designated 2 is of conventional construction which comprises flat panels of various thicknesses such as A5 or A" and has a series of pairs of regularly spaced rectangularly arranged apertures or openings 4, 4. Adjacent horizontally spaced openings 4 form a pair and therethrough receive the legs 5, 5 of an anchor element 6 which is made of spring steel round stock wire. The legs 5, 5 are horizontally aligned and are V-shaped in a horizontal plane and each leg comprises front, and rear portions 7 and 8 which converge outwardly into an apex 9 intermediate the ends of the leg. The rear portions 8, 8 of legs 5, 5 converge rearwardly and, as best seen in ice FIGURE 4, wedge as at 10 against the adjacent rear corners of the margins of the related openings 4, 4 thus biasing the anchor structure rearwardly and wedge the bight portion 12, which interconnects the forward ends of legs 5, 5 toward the front side 13 of the board 2. The rear or distal ends of legs 5, 5 are provided with upwardly projecting extensions or hooks 14, 14 which are angled upwardly and forwardly and each leg bears its upper ends as at 15 (FIG. 2) against the back side 16 of the board 2. These legs assist in biasing the transverse hanger member 12 toward the board.

The member 12, in applied position of the anchor as in FIG. 4, is curved in a horizontal plane and has its convex side 17 directed rearwardly and engages the forward side 18 of an upright portion 19 of a C-shaped strap 20 of a hanger generally designated 21. The rear side 22 of portion 19 bears flat against the fiat front side 13 of the board. It will be noted that by arranging the convex side rearwardly, the tendency for the portion 12 to straighten out causes the leg portions 5, 5 to be biased toward each other which enhances the wedging action of the rear portions 88 of the legs 5, 5 against the margins of the openings 4. The forward angled portions 7, 7 provide the requisite clearance for the legs 5, 5 at a, a (FIG. 4) so as not to bind against the forward edges 23, 23 of openings 4, 4.

The unstressed condition of the anchor portion is shown in FIGURE 5 wherein the bight portion 12 is shown straight. The legs 5, 5 when spread out are spring-biased toward each other.

The hanger 21 which is preferably formed of strap steel, comprises a pair of such [-shaped straps 20 which in addition to the upright portions 19 comprise an upper generally horizontal portion 24 which rests as at 25 upon the bight portion 13 of the associated anchor.

The lower end of each portion 19 is connected to a forwardly projecting base portion 26 which has a slightly upwardly curved forward end portion 27.

The base legs or portions 26 are interconnected adjacent to their forward portions by a cross-brace 28 which extends beneath both legs 26, each leg being apertured at 29. The stock taken from each aperture 29 is formed into, tabs 30, 31 which project under the front and rear edge portions 32, 33 of the brace 28 and spring bias the brace upwardly tightly butting the top side 34 of the brace against the undersides of the legs 26.

The end portions 35, 35 of the brace 28 are turned slightly upwardly and serve to embrace the sides 36, 36 of the rectangular container 37, while the front portions 27, 27 extend in front of the forward wall 38 of the container. The rear wall 40 of the container is underposed with respect to the upper legs 24.

The weight of the articles carried by the pans or containers cantilevers the hanger structure loading the curved bight portions 13 which then tend to straighten out. In addition these legs are urged downwardly toward the bottom edges of the openings 4 which further stresses them. Additionally the anchor assembly tilts about a horizontal axis whereby the portion 13 tends to move downwardly and thus the upper ends 15, 15 of hooks 14, 14 react against the back side 16 of the board 2 while the extensions 14 tend to bend backward. It will be observed that the extensions 14, 14 are related at an acute angle of about 45 to the plane of the legs 5, 5 and that the diametrical dimensions of the wire forming the anch r is such as to readily admit the extensions 14, 14 through the apertures 4 at the angles at which the extensions 14, 14 form the apices 45, 45 with the legs 5, 5.

The extensions 14, 14 also converge upwardly thus further resisting withdrawal through apertures 4, 4.

Thus a preferred form of the invention has been disclosed which serves equally well with boards of different thicknesses and with variations within limits in the spacings between the openings.

The structure is easy to apply and remove, simple to manufacture, is self-adjusting, and functions without the necessity of making any alterations in the mounting board.
